Jet 690180 Vertical Milling Machine 2HP 9x49 R-8

Product Description

The JET 690180 is a variable-speed vertical milling machine built for precision metalworking in machine shops and industrial maintenance environments. It features a 9 x 49 inch work table, an R-8 taper spindle, and a 2 HP single-phase motor rated for 115/230 volts. The variable-speed drive allows the operator to dial in spindle RPM without changing belt positions, improving workflow on varied milling operations. At 2,420 pounds, this is a full-weight knee mill intended for permanent floor installation. Licensed machinists, tool and die makers, and industrial maintenance technicians are the primary installers and operators.

The JET 690180 suits job shops, vocational training facilities, and industrial maintenance departments that require a general-purpose knee mill for face milling, end milling, drilling, and boring operations. The 9 x 49 inch table provides ample surface area for mid-size workpieces. The R-8 taper is the standard collet and tooling interface common across most American-market knee mills, making tooling sourcing straightforward for shops already running compatible equipment.

Key Features

• 9 x 49 inch work table with T-slots for workholding fixtures
• R-8 spindle taper — compatible with the most widely available collets and tooling in the industry
• 2 HP single-phase motor accepts 115V or 230V input
• Variable-speed head eliminates belt changes for RPM adjustments
• Full machine weight of 2,420 pounds for rigid, vibration-resistant cuts

Compatibility

Designed as an OEM-specification vertical knee mill accepting standard R-8 shank tooling, collets, and boring heads. No specific replacement or cross-reference compatibility was stated in the product data.

Installation Notes

Installation requires a licensed electrician to wire the motor for either 115V or 230V service per NEC requirements before operation. The machine must be leveled on a reinforced concrete floor adequate to support 2,420 pounds; anchor bolting is recommended for stability. Power must be fully de-energized and locked out before any spindle tooling changes, belt inspection, or gib adjustments. Do not operate without all guards in place and confirm the correct voltage tap is selected before initial power-up.
